<h2>Why is this an issue?</h2>
<p><code>partial</code> methods allow an increased degree of flexibility in programming a system. Hooks can be added to generated code by invoking
methods that define their signature, but might not have an implementation yet. But if the implementation is still missing when the code makes it to
production, the compiler silently removes the call. In the best case scenario, such calls simply represent cruft, but in they worst case they are
critical, missing functionality, the loss of which will lead to unexpected results at runtime.</p>
<p>This rule raises an issue for partial methods for which no implementation can be found in the assembly.</p>
<h3>Noncompliant code example</h3>
<pre>
partial class C
{
  partial void M(); //Noncompliant

  void OtherM()
  {
    M(); //Noncompliant. Will be removed.
  }
}
</pre>
